5x =15

x=15/5x=3

mark me as branliest

Step-by-step explanation:

Answer 2

Answer

• 3x+y-5=0--------------(i)
• y=5-3x-----------(ii)

• 2x-y-5=0-------(iii)

put y=5-3x in the equation (iii)

we get that,

• 2x-y-5=0
• 2x-(5-3x)-5=0
• 2x-5+3x-5=0
• 5x-10=0
• 5x=10
• x=10/5
• x=2

put the value of x=2 in the equation (ii)

we get that,

• y=5-3x
• y=5-(3×2)
• y=5-6
• y=-1

$\therefore$The value of x=2 and y=-1
